| 20080204156 | Measuring threshold voltage of transistors in a circuit - In one embodiment, the present invention includes an oscillator to generate a first frequency and a second frequency. The oscillator includes a plurality of stage cells, each stage cell including a first transistor of a first polarity and a second transistor of a second polarity, each coupled between a first voltage node and a first intermediate node and an inverter coupled to the first intermediate node. In operation, a difference between the first frequency and the second frequency is proportional to a threshold voltage of the second transistor. Other embodiments are described and claimed. | 08-28-2008 |
| 20110279149 | METHOD, APPARATUS, AND SYSTEM FOR MEASURING ANALOG VOLTAGES ON DIE - An analog-to-digital converter (ADC) suitable for measuring on-die DC or low frequency analog voltages may include a ring oscillator having a group of circuit cells successively and circularly coupled. Under certain circumstances, the ring oscillator may produce an output frequency that corresponds substantially linear to the input voltage. Other embodiments may be disclosed or claimed. | 11-17-2011 |
| 20120062401 | ON-DIE DIGITAL-TO-ANALOG CONVERSION TESTING - In one embodiment, an analog-to-digital conversion in an integrated circuit is evaluated by an on-die testing circuit. For example, the on-die test circuit 370 can characterize one or both of the linearity and monotonicity of the digital-to-analog conversion. The value of a conversion output for a digital input code may be compared to the value of a prior conversion output of a prior step to provide digital difference values for each step of a sweep of digital input codes. Digital difference values may be compared to one or more predetermined limits to provide one or more pass/fail tests on-board the die. Other embodiments are described and claimed. | 03-15-2012 |

| 20110088492 | Automated cascade impactor - An automated cascade impactor comprises an extension mechanism operable to couple to a plurality of impactor stages. The extension mechanism is operable to compress and separate impactor stages of the plurality of impactor stages via automation. The system provides a plurality of isolation stages operable to be automatically inserted between respective impactor stages when the impactor stages are separated by the extension mechanism. The system provides the plurality of isolation stages to be automatically compressed between impactor stages to isolate each impactor stage from at least one adjacent impactor stage. The plurality of isolation stages is operable to be automatically uncompressed and removed from between the impactor stages. The isolation stages allow automated extraction of particulate matter, cleaning and drying of interior surfaces of each impactor stage. | 04-21-2011 |

| 20100080980 | MOLDING PROCESS FOR CORE-CONTAINING COMPOSITES AND COMPOSITES FORMED THEREBY - A process for producing composite structures having a core between resin-impregnated composite layers, and composite structures formed by such a process. The process uses non-impregnated fabric layers and a core layer placed on a mold such that the core layer is between at least two fabric layers, a first of which is disposed between the mold surface and a first surface of the core layer, and a second of which is disposed at a second surface of the core layer. The second fabric layer is then infused with a resin, which flows through holes in the core layer into the first fabric layer, such that the first and second fabric layers are uniformly impregnated with the resin and the core layer is not. The resin is then cured to cause the impregnated first and second fabric layers to bond to the core layer. | 04-01-2010 |
| 20100196654 | PROCESS FOR PRODUCING COMPOSITE LAMINATE STRUCTURES AND COMPOSITE LAMINATE STRUCTURES FORMED THEREBY - A process for producing resin-impregnated laminate composite structures that comprise a closed-cell core between resin-impregnated fabric layers, and preliminary and composite structures formed by such a process. The process includes stitching a roving in a preliminary structure that includes the core so as to structurally reinforce the core. The roving passes through through-holes in the core and traverses opposite outer surfaces of the preliminary structure. The outer surfaces of the preliminary structure traversed by the roving may be defined by outer surfaces of the core, or the preliminary structure may further include two or more fabric layers on outer surfaces of the core such that the core is between the fabric layers, the roving passes through one or more fabric layers, and at least one of the outer surfaces of the preliminary structure and traversed by the roving is defined by a fabric layer. | 08-05-2010 |
| 20110167781 | TURBOMACHINE NACELLE AND ANTI-ICING SYSTEM AND METHOD THEREFOR - An anti-icing system and method for an aircraft engine nacelle. The nacelle has an inlet lip that defines a leading edge of the nacelle and has a cross-sectional shape and oppositely-disposed exterior and interior surfaces. An anti-icing system contacts at least the inlet lip of the nacelle. The anti-icing system includes at least one heating element having a cross-sectional shape that conforms to the cross-sectional shape of the inlet lip and in which carbon nanotubes are oriented and arranged to conduct electrical current through the heating element. Passing an electrical current through the heating element causes Joule heating of the heating element and heating of the inlet lip by thermal conduction. | 07-14-2011 |
| 20110297325 | PROCESS AND APPARATUS FOR PRODUCING COMPOSITE STRUCTURES - A process and apparatus for producing perforated composite structures, such as acoustic skins suitable for aircraft engine nacelle and duct components. The process includes placing a mat member, a non-impregnated fabric member, and a resin film on a tool surface so that pins disposed on the mat member project through the fabric member and resin film to define holes therein. The fabric member is between the mat member and resin film, and the fabric member and resin film define a stack that conforms to the mat member and tool surface. A caul member is then placed on the stack so that apertures in the caul member are penetrated by the pins. The stack is heated to melt the resin film and cause molten resin to infuse the fabric member and yield a resin-infused fabric stack, after which the molten resin within the resin-infused fabric stack is at least partially cured. | 12-08-2011 |
